Web20 aug. 2024 · One way to assess the quality of 3D printed parts is to probe them with the X-ray beams generated by an accelerator. But it’s difficult to secure access to those accelerators for this kind of fundamental research. What’s needed is a cheaper – and therefore more plentiful and available – form of accelerator. WebA laser beam generated axially in a disk laser can have a very high beam quality (as low as 4mm*mrad for the lower power materials processing lasers). Although the fact that the disk is very thin allows very efficient cooling, it also means that only a small fraction of the pump light is absorbed as it passes through the disk.
